The MailChimp APIs

Ever since we birthed our original API, we've grown - a lot. Below are our current API offerings - inside each you'll find a mix of these things, as appropriate:

  • In-depth documentation on using each one
  • Downloads and links to Wrappers to jumpstart your development
  • How-tos specific to each one

Woah! If you haven't worked with Web APIs before, it is highly suggested that you read our general Getting Started information.

The API - also referred to as the API proper or MCAPI (MailChimp API), this allows for List and Campaign Management along with touching tons of other things in your account. This is probably what you want.
OAuth2 - handling people's usernames and passwords is a nasty thing that no one should do - OAuth2 fixes that.
STS API - aka, Simple Transactional Service. It is mostly a pass-through to Amazon's SES and is our pure-transactional email offering.
Export API - normal API calls are buffered and can only return so much data. Methods here allow you to stream potentially large amounts of data out of our servers.
Webhooks - are Webhooks. Stuff happens and we send you data about it.
